Hi I am new to reefkeeping and at present time I am cycling my first reeftank. I am using Salifert magnesium test but having trouble! The colour wont change from pink to blue when I empty the whole second syringe into the tube so my question is this : does it mean that my magnesium is high or low? I used ro/di water and Redsea coral pro salt which says that is has a mag of 1340 on the bucket.
Thanks in advance.
